	COMMENTS	`This classification is specifically concerned with changes to examples that leave them sortable, as there are almost always ways of adding details to a BP's examples that make them unsortable.` `Another version of this Bongard Problem could be made about adding white (erasure of detail) instead of black (addition of detail).` `Another version could be made about adding either white or black, but not both.`
